Application filed Uetober at, 1911. serial Ito. states.

To all whom it may concern Be it known that T, GEORGE W. Ensure, acitizen of the United States, residing at Bayonne, in the county ofHudson and State of New Jersey, have invented certain new and usefulImprovements in Machines for Drying Cartons; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use-the same.

This invention relates to drying machines, and especially to that typeof machine which may be connected to and operated by a coating machine,such as is described and claimed in my copending application Serial No.656,438 filed Uctober 21, 1911, and entitled machine for coatingcartons.

The object of this invention is to provide a machine of this characterthat will receive a carton or the like after it has been thoroughlycoated with paraffin, and dry thesame with certainty and expeditiously.

A further object is to provide a machine that is comparatively simple inconstruction and so arranged as to take up as small floor. space aspossible.

With these and other objects in view, the invention consists in thenovel details of'construction and combinations of parts more fullyhereinafter described and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of thisspecification in which like numerals designate like parts in all theviews :Figure 1 1s, a perspective view of myimproved machine shownconnected to and operated. by a paraffin coating machine; Fig. 2 is aside elevational view of the arts shown in Fig. 1, but showing part 0the parafin coating machine broken away for the sake ofclearness; Fi 3is an enlarged partly sectional detail si e elevational View of aportion of the machine, and showing a part of the driving mechanism;Fig. 4 is an enlarged detail side elevational view of the top part ofthe machine with the hood broken away; Fig. 5 is a horizontal crosssectional view taken on the line 5--5 of Fig. 4t and looking down; Fig.6 is a cross sectional view taken on the line 6-6 of Fig. 3, and lookingin the direction of the arrows;

Fig. 7 is a cross sectional view taken on the line 7 -7 of Fig. 2; Fig.8 is a cross sectional view taken on the line 8-8 of Fig. 3,; and, Fig.9 is a detail side elevational View of the system of piping employed.

1 indicates a parafiin coating machine, such as that disclosed in myapplication above, and provided with the parafin wheel 2 (Fig. 2) whichis adapted to receive cartons 5 from the suppl chute 3, and immerse themin a hot bath 0 parafiin t. This paraffin wheel 2 is revolved. throughsuitable mechanism (Fig. 1) by the electric motor 6 and the coatedcartons delivered to the conveyer 17, all as will be clear from myapplication above.

Connected to the side of the coating machine 1 is my dryin machine 7,which contains the conveyer 1 carrying the wet cartons from the parafinwheel 2, and serving to dram and dry them, as will now appear. Theframework of the drying machine rises at an angle of about 4:5 degreesand comprises the short standards 8, and the long standards 9 and 10rigidly connected bythe longitudinal bars 11 (Fig) 1) and longitudinalbars 12 (Figs. 6 and Rigidly mounted on the top of the angle bars 12 isa chute 13 comprising the drain ing chamber 14: for the cartons and theheating chamber 15, heated by thegas burners 150. This chute is soconstructed that the flanged top 130 overla s the sides and seats itselfin the grooves o the extensions 132 so that it can be removed whennecessary, and yet form practically an air tight joint.

Mounted within the draining chamber and adapted to travel on the anglebars 16 with which said chamber is provided, is the endless conveyer '17provided with a series of cross rods 18. This conveyer travels at theupper end of the chute over the sprockets 19, mounted on the shaft 20,(Fig. 4) held in the bracket 21, and at the lower end of the chute overthe sprockets 22 (Fig. 2) mounted on the shaft 23 held within theparafin machine 1, and operated by the motor 6, by means of theconnections shown and comprising the s rocket 24:.

The top run 0 the conveyer 17 in passing from the paraflin machine tothe drying machine or from the horizontal to the tipwardly inclinedposition, is; guided by the inverted angle bars 25 (Fig. 7) and thelower run is guided by the idler sprockets 26 mounted on the shortstandards 8 (Fig. 2).

Connected to the angle bars 12 and sus pended therefrom are the straprods 27 (Figs. 4 and 6) for supporting a second chute 28 immediatelybelow the chute 13. This second chute comprises a receiving chamber 29,and a heating chamber 30 (Fig. 3) to accommodate the gas burners 301.Cartons after being drained bottom up in the first chute are deliveredto this second chute bottom down, for a purpose and in a manner to bedescribed below.

Mounted within this second chute 28 and adapted to travel within thechamber 29, on the angle bars 31, are a set of second endless conveyerchains 32 provided with a series of cross rods 33. These chains orconveyors 32 travel, at their upper ends, over the sprockets 34 (Fig. 4)mounted on the shaft 35 held within the brackets 36 to the top framework,of the machine, and at their lower ends over the sprockets 37 (Fig. 3)mounted on the shaft 38 held within the brackets 39 suspended from theangle bars 12. These said conveyer chains 32 are also adapted to beoperated by the conveyers or chains 17 through the gear 40 (Figs. 4 and5) mounted on the shaft 20 meshing with the gear 41 mounted on the innerend of the stud shaft 42, sprocket wheel 43 mounted on the outer end ofthe stud shaft 42, and sprocket chain 44 and sprocket 45 mounted on theouter end of the shaft 35.

Connected to the longitudinal and horizontal bars 11 by the supports 46(Figs. 2 and 8) are the channel irons 47 which are adapted to carrv athird set of endless conveyer-ea oz chains 48 adapted to receive thecanon iron. the second conveyers, as will appear below. These chainstravel at their outer ends over sprockets 49 (Fig. 2) mounted on a shaft50 held within the horizontal bars 11, and at their inner ends oversprockets 51 mounted on a shaft 52 held in the brackets 53 suspendedfrom the angle bars 12 of the machine. These said third conveyers orchains 47 are adapted to be operated (Figs. 3 and 6) by the secondconveyer chains 32 through the gear 54 mounted on the shaft 38, meshingwith the gear 55 mounted on the stud shaft 56, sprocket wheel 57 rigidwith the gears 55, sprocket chain 571, and sprocket 58 mounted on theend of the shaft 52.

59 and 60 indicate guard plates (Figs. 2, 4 and 5) connected to the topof the chute 13, and to the frame of the machine, which together withguide bars 61 located within the second chute, and connected at theirlowerends to the strap rods 27 and at their upper ends to the bracket 21serve to guard and to guide the cartons as they are delivmeager);

ered from the first conveyors or chains 17 to the second conveyors orchains 32.

A hood 61 is mounted on the top of the machine and connects to a pipe 62for carry ing oil any gases or fumes that may arise.

63 (Figs. 1, 2 and 3) indicates a semi cylindrical guard provided with aheating chamber 64, having the gas burner 65 (Figs. 2, 3 and 9). Thisguard is located at the delivery or lower end of the chute 28, andbetween the brackets 39 for the purpose of guiding and changing thecartons from their angular position on the second conveyer chains 32 toan upright position on the third conveyer chains 48.

Longitudinally disposed, horizontal guard rods 66 held in uprights 67mounted on the horizontal bars 11 prevent the cartons from falling offthe third conveyer chains 48 while they are being transported.

All of the heating chambers are provided with the necessary openings,not shown, for admitting air to the burners.

The gas burners 150, 301 and 65 (Figs. 2, 6 and 9) are connected throughpiping to the gas supply pipe 68. Additional gas burners 69 and 70 areplaced in the piping for heating parts of the machine not otherwiseinclosed by the heating chambers. All of the gas burners are controlledby the valves 71 and 7 2 or other suitable means.

Mounted on the fr ime of the machine be tween the standards 9 and 10 andsurround ing the third conveyer chains 48 is a compartment 73 (Fig. 2)which receives a continuous blast of air from the fan 74. 013' eratedfrom any source of power, and which serves as a chamber for furtherdrying and cooling the cartons.

A drip pan 75 (Figs. 1 and 2) is mounted on the framework of the machimbel w the second and third conveyers for uivll L :in paraffin that maydrop and convey it With into the parafiin coating machine. Door. 76 and77 are also provided on the sides of tin chute 13 for lighting th g .sbin-nus 150.

The operation of tlll' machine is as rh lows :-Paper cartons or thelilac after the; have been thoroughly coated in a parafiin coatingmachine, such as l, are delivered antomatically to the conveyer chains,as disclosed in my application above, of the drying machine. The crossrods 18 on the conveyer chains 17 carry said cartons u the heated chute13, and if they were originally placed on the chute 3 of the coatingmachine with their bottoms all to the right, as seen in Fig. 1, theywill be carried around by the wheel 2 and delivered to the conveyor 17with their bottoms in the same direction. But, since the conveyer 17extends upwardly and at substantially right angles to the plane of thewheel 2, the cartons when delivered to said conveyer, will have theirbottoms gradually raised and their open mouths inverted,

nraaeet an that they will be drained of their surplus parafin.

After reaching the top of the chute, however, the cartons are carriedover the end thereof bottom foremost, and are guided by the plates 60and rods or bars 61, onto the second conveyer 32, which receives thembottorn down. In other words, all parafiin that is not needed in thewalls of the cartons is drained out while on the first conveyer, and anysurplus that may still stick to the walls is drained back to the bottomseams while on the second conveyer. In this way, the bottom seams aresupplied with an extra quantity of paratfin at a minimum cost, as willbe clear from Fig. '3 of the drawings.

4 But, this extra paraflin should beevenly distributed around the bottomseams, and to accomplish this end, the cartons 5 are delivered from thesecond conveyer 32 to the third conveyer t8, while their position ischanged from an inclined one to an upright position bottom down. Sinceduring all of the above movements, the chutes are kept sufiiciently hotto permit the parafin to flow easily, the surplus paraffin left insidethe carton, will not only be evenly distributed around the bottom seams,but no more paraflin will be left on the walls of the carton than isnecessary. As soon as the above results have been accomplished, thecartons are cooled in the chamber 73, from which they'may be collectedor delivered in any suitable manner.

It is obvious that those skilled in the art may vary the details ofconstruction, as well as the arrangement of parts, without departingfrom the spirit of my invention and therefore I do not wish to belimited to the above disclosure except as may be required by the claims.

What I claim is 1. In a carton drying machine, the combination of aninclined conveyer; rotary means for feeding wet cartons on to saidconveyer so their bottoms will point upwardly; means forcatching thedrippings from said wet cartons while on said inclined conveyer; asecond conveyer associated with said inclined conveyer; means fordelivering said cartons from the first to said second conveyer andreversing said cartons during the delivering operation so that theirbottoms will be down on said second conveyer; a third conveyer; andmeans to deliver said cartons from the second to said third conveyer andcausing said cartons to assume a vertical posltion with them bottomsdown on said third conveyer, substantially as described.
